LIST OF THE LBPIDOPTERA OF WEI-HAI-WEI. 173 



The scientific value of collections thus uniformly labelled 

 would, I think, be increased, and reference, at least, much 

 facilitated.

A PRELIMINARY LIST OF THE LEPIDOPTERA OF 

 WEI-HAI-WEI. 



By Thomas Bainbrigge Fletcher, R.N., F.E.S. 

 (Continued from p. 156.) 



Fam. PiERiD^. 

 Sub-Fam. Pierin^. 



Pieris lapce, L. — Common all the summer near cultivated ground 

 round the villages. They seem mostly referable to var. orientalis, 

 Oberth. ; the females as a rule have the basal black markings much 

 developed (var. crucivura). I noticed that on wet days they often settle 

 on willow-leaves, evidently selecting these because they are of a light 

 tint, and match the under surface better than would most other leaves. 



Pieris canidia, Sparrm. — Common in May. 



Poiitia daplidice, L. — Common all the summer; there seem to be 

 two emergences, one in May and the other in August, but the species 

 is to be found all tiirongh the warm season. It has a decided prefer- 

 ence for a sandy beach overgrown with a small Convolvulus. 



Sub-Fam. Callidryin^. 



Eurymus {Colias) hijale, auct. (= kirbii, Lewis). — Common in April 

 and May, and again from September until the cold weather sets in. 

 A white form of the female is fairly common. These Wei-hai-wei 

 specimens agree best with var. elivesii, Butl., of the form (? sub-species) 

 poliographiis, Mots. 



Terias aneinove, Feld., var. mariesii, Butl. — One specimen ; Leu- 

 kung-tao, 4th September, 1898. 



Fam. EQmTina:. 

 Sub-Fam. Equitin^e. 



Jasoniades (Papilio) xuthns, L. — I only met with this species on one 

 occasion, on 28th August, 1898, when it was common in Leu-kung-tao 

 along the hills. This would be the second brood. In Japan, I have 

 taken the first brood (var. xuthidus) at Nagasaki in April, but have not 

 seen it at Wei-hai-wei. 



Achivus [Papilio) machaon, L. — Fairly common, especially round 

 hill-tops at an elevation of from five hundred to a thousand feet. 

 There are two emergences, the first appearing at the beginning of May, 

 the second about the middle of August. The spring brood is typical 

 machaon, the aestival is decidedly var. asiatica, Men. ; it is, however, of 

 normal size, and does not approach the large form hippocrates, Feld.
